Chaetodon octofasciatus

Datasheet

General Description

The Eightband Butterflyfish (Chaetodon octofasciatus) falls under the Chaetodontidae family, known for their vibrant colors and patterns. Belonging to the Chaetodon genus, some species are grouped in complexes due to their striking resemblance, with variations in needs and origins. Indigenous to the East Indies, the Philippines, Great Barrier Reef, and extending to the Indian Ocean, this species displays a unique eight-banded pattern, distinguishing it from similar genus members.

Aquarium Suitability

Considered not suitable for most home aquariums due to its challenging care requirements and delicate nature, the Eightband Butterflyfish demands specific conditions to thrive. With an inclination towards aggression compared to its counterparts, this species may display territorial behavior, especially towards similar species. Not reef-safe, it may pose a threat to clam species and generally necessitates an established and spacious tank to accommodate its swimming habits adequately.

Demands, Care, and Hardiness

Boasting an average hardiness level, the Eightband Butterflyfish is notoriously challenging to maintain in captivity, often struggling to acclimatize and adapt to artificial environments. Requiring frequent feedings, especially during initial introduction, this species has a particular affinity for coral polyps, making varied and species-appropriate diets essential for their well-being. The need for a well-established aquarium with an abundant micro-life ecosystem adds to the complexity of its care regimen.

Reef Suitability

Categorized as not reef-safe, the Eightband Butterflyfish may pose a threat to coral and invertebrate species typically found in reef environments. With a documented appetite for tubeworms and a tendency to nibble on clams, this species is incompatible with most reef setups.

Aquarium Setup

When setting up an aquarium for the Eightband Butterflyfish, it is crucial to provide ample hiding spots, such as live rock crevices, to alleviate stress and facilitate natural behavior. A tank size of at least 500 liters is recommended, along with stable water conditions falling within specific parameters: a temperature range of 22.2-25.6°C, a pH of 8.1-8.4, and a salinity level of 1.020-1.025. Additionally, ensuring a diverse and abundant food supply is vital for the long-term health of this species.

Behaviour

Known for its potential aggression towards similar species, the Eightband Butterflyfish exhibits territorial behavior and may require careful consideration when selecting tank mates. While generally peaceful towards other fish, this species thrives in environments that mimic its natural habitat, providing opportunities for swimming and exploration.

Feeding and Diet

The dietary preferences of the Eightband Butterflyfish primarily revolve around coral polyps, posing challenges for aquarists aiming to transition them to alternative food sources. With a recommended diet consisting of larger crustaceans, invertebrates, zooplankton, and small crustaceans, ensuring a varied and nutrient-rich menu is crucial for their nutritional needs.

Dimorphism

Although not specified, captive reproduction of the Eightband Butterflyfish typically involves mimicking their natural feeding behaviors and providing live SPS or LPS corals as a primary food source to encourage breeding.

Habitat and Distribution

Natively found in the Indo-West Pacific region, including areas like the East Indies, the Philippines, Papua New Guinea, the Great Barrier Reef, the Solomon Islands, Palau, China, and extending to the Indian Ocean, the Eightband Butterflyfish thrives in tropical marine environments with diverse coral ecosystems.
